I am 21 and have been wearing contacts for about 9 years. During that time, I have not had a backup set of glasses to wear when my contacts are out. I finally got sick of not being able to see at night because I am pretty "blind", at least in my opinion. My current contact prescription is -4.75 on both eyes. I recently went to the optometrist to get glasses. I also asked for a prescription for my contacts so that I can buy those when I need more because I can still see well out of my current contacts and still have a few boxes. The new prescription for my glasses were R -6.00, L -6.00. PD is 29, 32. The frames are chose are pretty narrow. The new contact prescription was -5.25 for both eyes. I really don't know what this all means so I hope this is enough information. Anyway, I can't really wear these glasses. They give me an instant headache and make me feel nauseated. When I wear them, it looks like everything is kind of 3D and things bow in. For example, when I look at a straight horizontal line, like where the ceiling meets the wall, it bows down at me. When I look ahead, straight vertical lines to my sides bow inward like this ( ). Also, when I look around, everything seems pretty jumpy. I went back to my eye doctor and they checked my glasses and the prescription was what he measured. So he redid my exam and said the prescription was a bit too strong and that is what was giving me the 3D and bowing effects. Everything looked OK when I was looking throught the machine when he found my prescription, but I can't look around at thingsthrough it, just straight ahead. So, when I got my glasses back (through mail b/c I am a college student living away from home where my eye doctor is) they were slightly better, but still not good. I don't even want to wear them. I haven't got new contacts because, as I said, I still have some and I can see fine. So I wonder what is wrong, why are my glasses doing this? Could it be the frames I chose, or that the prescription is still too strong? If the prescription is still too strong, when looking through the machine, how can I tell the difference between right, and too strong? What can I say to my doctor to help him diagnose the problem? Should I try a different doctor? Please help, I really would like to be able to wear my glasses. Thanx so much.
